BICYCLE CR TRICYCLE ATTACHMENT,

SPECIFICATION forming part of Letters Patent N0. 589,305, dated August31, 1897.

Appiicaion ne@ Anglia 21, 1896.

T o @ZZ whom it may.; concern; l

Be it known that I', HIPPOLYTE SCHNEIDER, a citizen of the United Statesof America, residing at Pittsburg, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inBicycle and Tricycle Attachments, of which the following is aspecification, reference being had therein to the accompanying drawings.Y

This invention relates to certain new and useful improvements inbicycle'attachments and will also be applicable to tricycles and likevehicles.

The principal object of my invention is to construct a crank whereby thestroke of the same may be shortened or lengthened by the rider at willwithout dismounting from the wheel or decreasing the speed to accomplishthe above result, thus affording the rider the advantage of a greaterleverage for riding o n roads having considerable' grade, making thework easier, tending to lessen the strain on the rider, and to aconsiderable extent obviatingthe danger of over exertion. l

Vith the above and other objects in view the invention finally consistsin the novel construction, combination, andarrangement of parts, to behereinafter more specifically d'escribed, and particularly pointed outin the claim.

In describing the invention in detail'reference is had to theaccompanying drawings, forming part of this speciication,and whereinlike letters of reference indicate similar parts throughout the severalviews, in which-- Figure l is a side view of the crank,` and Fig. 2 is asimilar View With the pedal and attachment in position. Fig. 3 is asideview of the reverse side from that shown in Fig. 2. Fig. 4 is a sideview of the crank and attachment With the pedal removed. Fig. 5 isafront View of the pedal. yFig.f 6 is afront view of the crank andattachment with the pedal removed. Fig. 7 is a top plan view of thepedal broken away. y Y

Referring to the drawings by reference-let- Y ters, @represents thecrank,which is secured to the crank-shaft in any suitable manner and isprovided on one edge vwith notches l) b.

desired position.

seria No. 603,490. v(No model.)

` A casing or box c is adapted to slide on the crank a, oneside of saidcasing consisting of a plate CZ of greater width than the y'casing andto which is secured the pedal-shaft e. A trip-lever consisting of ahorizontal portion f and upwardly-extending portion f is pivotallysecured to the plate, said horizontal portion carrying a pin g, whichengages through a notch g in the plated and casing c and in the notch bof the crankto hold the casing in the A spring 7L is attached to therear end of the portion fand to the plate CZ near the top to keep thispin normally in engagement with the crank. A stop-pin h' is securedinthe plate CZ back of the trip-lever to limit the throwof the lever f',and a coilspring 7c is attached to the crank a near the inner end and tothe casing c to return the pedal from the long to the short stroke whenthe catch is released, said crank having an offset Zo on the one sideand a pin k2 on the other side to limit the backward movement of thecasing, and a pin 7c3 in the front end of the crank limits the forwardmovement.

The pedal Z, which is secured to its shaft in any suitable manner,carries a brace Z', to which is pivotally'attached a lever Z2, adaptedto be forced in engagement with the lever f `to operate the same, and aspring Z3, attached to the lever Z2 and the pedal, holds the said levernormally out of engagement.

We will now assume for the purpose of illustration that the parts `haveY been secured in their respective positions and that the crank isattached to its shaft on the machine, the pedal being at the shortstroke, as shown in Figs. 2, 3, and et, and itis desired to extend thesame and use the long stroke. The rider presses the side of the footagainst the lever Z2, forcing the lug of the same toward the crank andinto engagement with the trip-leverf, forcing the pin g out of itsengagement with the casing and crank, when by pressing downward with thefoot the rider forces the pedal outward along the crank until the springg comes in contact with the outer slot b., when kit will engage and holdthe pedal in'this position. To release the same and again employT theshort stroke, the lever Z2 is again forced into engagement with thelever f', releasing the catch g, and when the pressure of the foot IOOon the pedal is relieved the coil-spring 7U' will return the pedal toits short stroke, when the pin g again engages and retains same.

Having fully described my invention, what I claim as new, and desire tosecure byLetter-s Patent, is-

In a device of the character described, a crank provided with notchesalong one side,a casing slidable on the crank,a plate of greater Widththan the casing forming a side thereto, a pedalshaft secured to saidplate, an angular trip pivoted to the plate, a pin carried by theangular lever slidingin an opening in the plate and engaging one of thenotches 0f the crank, a spring connecting one end of the angular leverto the plate, a coil-spring connecting the casing to the inner end ofthe crank, an offset and pin on the crank to`
